To all whom it may concern.-

Be it known that I, GHAUNCEY W. GAY, a citizen of the United States of America, and a resident of est Springfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Paper-Machines, of which the following is a full, clear, and exact description.

This invention relates to machines for surface-finishing paper, and has for one of its objects the acquirement of means whereby the machine is or may be rendered adaptable for imparting the desired one of a number of qualities of surface-finishing; and one principal object of the invention is to render the machine efficient not only for imparting a cloth-like surface finish to either or both sides of the paper, but for rendering the so-surfaced paper more or less bright or glossy, as may be required in the trade for the finished prodnot; and a further object is to organize the machinefor the purposes indicated, to the end of extreme simplicity in construction and efficiency in operation.

The invention is characterized to a large extent by the inclusion therein of sidewiseadjacent rotary cylinders having peripheral surfacing portions with longitudinal niches therein, grippers within and coacting with marginal portions of said niches, and gripperoperating means whereby the grippers carried by one cylinder after having carried the sheet of paper suitably far around so that its leading edge is brought adjacent the grippers of a succeeding cylinder will be opened, permitting the. leading end of the sheet to be taken by the grippers of the succeeding cylinder, and thereby carried to and between all of the surface-finishing cylinders and substantially as illustrated and described in Letters Patent of the United States granted tome December 20, 1904, No. 778,126.

This invention or new improvement consists in the formations of parts and the combinations thereof, all substantially as hereinafter fully described, and set forth in the claims.

The improved machine is illustrated in the accompanying drawings, in which Figure 1 is a plan view. Fig. 2 is an elevation of the machine as seen beyond the plane indicated byline 2 2, Fig. 1. Fig. 2" is a perspective View showinga portion of a rotary cylindrical gripper-carrying part which coacts with one of the surface-finishing cylinders in the delivery of the paper sheets away therefrom. Fig. 3 is an elevation of a portion of the side frame, showing the adjustability and means for adjustment of the surface-finishing cylinders. Fig. 4 is a sectional view and end elevation through adjacent portions of the final pair of surfacing-cylinders. Figs. 5, 6, 7 and 8 are sectional views of portions of the cylinders, illustrating features hereinafter referred to.

Similar characters of reference indicate corresponding parts in all of the views.

In the drawings, 10 represents a massive rigid rectangular frame having in the recesses opposite sides thereof, as represented at 12, the journal-bearing blocks 21, 22, 23, and 24 for the end journals 25 of the surface-finishing cylinders 1, 2, 3, and 4, all axially horizontal and parallel, located at the same level and running with their peripheries adjacent-that is, almost, if not quite, in rolling contact.

15 represents the driving-shaft, having driving-pulleys 16 thereon, and said shaft 15, through gear-wheel 17, which meshes into gear-wheel 18, drives the counter-shaft 19. Said counter-shaft 19 has a pinion-gear 28 thereon, which meshes into a gear-wheel 29 on shaft 2, and said gear-wheel 29 meshes into a similar-sized gear-wheel 30 on cylinder 1 and into a like gear-wheel 32 on cylinder 3, and with said gear-wheel 32 a same-sized gearwheel 33, afiixed on the journal-shaft of cylinder 4, meshes, said train of gearing causing all of the surfacing-cylinders'to rotate in unison and in the direction of the arrows on Fig. 2 at the same rate of speed.

Cylinders 1, 2, and 3 are constructed with longitudinal niches 35, one of which is shown in Fig. 4, and a gripper-carrying rock-shaft 36 is located and longitudinally arranged in a niche of each cylinder having journal-supports through the cylinder end head 37, which make the end boundaries of the niches, and on one end of each rock-shaft is a short lever 38, provided with a friction-roll 39 to coact in the revoluble movement of the lever in unison with the cylinder and a cam affixed on the inner side of the machine-frame, and in the drawings the several cams for operating the gripper rock-shaft are represented by 40.

42 represents the gripper-fingers.

It is not required that the fourth cylinder be provided With grippers and gripper-operating means, as the paper after having been fed through and between the first three cylinders and is emerging in an upward direction from between the third and fourth cylinders is edgewise grasped by a series of grippers 42 on the rock-shaft 36, which is carried between the axis and periphery of a rotary cylindrical carrier and has the lever 38, the roll of which coacts with the fixed cam 40, supported at one inner side of the machine-frame. The said rotary cylindrical part in this particular case consists of a horizontal shaft 46, mounted in journal-brackets and ranging horizontally over and parallel with surface-finishing cylinder 3, together with the series of disks 47, running peripherally with the cylinder 3, the webs thereof constituting supports for the gripper-carrying rock-shaft 36, while the gripper-lingers 42 close against and open from laterally-extending lugs 48, which are formed as integral parts of the disks 47. This makes an open-work and light construction, which is preferable to a solid cylinder which, as is manifest, might be provided-for instance, in the form of one of the surface-finishing cylinders having a niche therein for the accommodation of the grippercarrying rock-shaft.

All of the gripper-carrying rock-shafts in this machine have thelever extensions 44, connected to which are the springs 45, the action of which is to impart rotational movements to the rock-shaft to hold the grippers closed at all times excepting when they are positively open by the coaction of the rock-shaft levers 38 with the cam respectively provided and suitably'located therefor.

The construction of the cylinders with niches, rock-shafts, spring-closed grippers, and gripper-operating cams are in this machine substantially the same as "fully described and shown in my aforesaid Letters Patent, dated December 20, 1904, and it is not considered necessary or desirable to herein include a more extended description of the construction and relative arrangement of the sheets of paper to be finished through the succession of cylinders.

The first and second cylinders have their peripheral surfaces covered with a textile fabric such, for instance, as cotton or linen cloth, and having a texture corresponding with which it is desired the surfaces of the finished sheets of paper shall have. In practice I employ three sheets or layers of the textile fabric 50, the marginal portions thereof being carried within the niches 35 and engaged by and clamped between the clampingplates 52, which, as shown at 54 54, Fig. 4, have ribbed and grooved engagements at the opposite side walls of the niches or recesses 35, and said clamping-plates are held in their fabric-securing positions by the clampingscrews 55, and in the machine equipped as here illustrated the pair of cylinders 3 and 4 are made with the layer of cloth over and next to the smooth metallic bodies ofthe cylinders, and each of these layers of cloth is overlaid by very thin sheets of copper or other suitable metal, the combined cloth and copper sheets being taut and have their edge portions clamped in the recesses or niches of the cylinders, as shown in Fig. 4, this means of clamping prevailing in all of the cylinders. By running the machine in a preliminary manner without passing sheets of paper therethrough and for a short while and with the cylinders set for hard peripheral bearings one against the other the copper covering-sheets are made to conform to the inequalities in the surface of the cloth thereunder and acquire surfaces like those of the textile fabric.

In the action of surface-finishing the paper, the paper in passing between the cloth-surface cylinders 1 and 2 derives a cloth-like but dull surfacing on its opposite sides; .but these sheets of paper receiving next the rolling pressure between the metallic surfaces of the third and fourth cylinders, which surfaces have the inequalities corresponding to those in the cloth, is rendered bright or glossy with, however, necessarily no diminution in the multiplicity of relatively intermediate minute depressed and raised surface portions.

Quite a number of variations may be made in the surfacing equipments of the several cylinders-as, for instance, all of the cylinders may have external coverings of cloth for acquiring a dull or dead surface finishing of the paper, or the second and third cylinders may have absolutely smooth peripheral surfacing portions, whereby the paper after pass ing through-and between the cloth-covered first pair of cylinders and having imparted the cloth-like surfacing thereto may by running between the smooth metallic surface second pair of rolls be rendered bright and glossy with a partial smoothing of the cloth-finished surfaces, or, again, all of the rolls may have metallic peripheral surfacing, all or some thereof made with the cloth-like inequalities or made smooth.

In the construction of the cylinders the bodies thereof are made integral with the journals and grooved longitudinally through from end to end to constitute the aforementioned niches, which give space for occupancy of the grippers and the rock-shafts which carry them. Disk-shaped end heads 37, having central circular apertures, are brought to place about the end journals and against the ends of the cylinders and are screwed in place thereon.

These end heads are peripherally continuous, so that as the recessed portions 35 of the rolls in rotation come together the rolls are prevented from violently sidewise impacting one against the next, and thus it is insured that the machine will run evenly for the most uniform surface-finishing pressure on the paper, also that jar and noise are prevented, and that the life of the machine is materially increased.

As before stated, the journal-bearing blocks 21. 22, 23, and 24 are located in opposite side recesses 12 in the machine-frame, the upper and lower walls of which recesses are parallel. The journal-block 22 for the second cylinder is rendered immovable by being sidewise in contact against the fixed block or partition 60. The journal-block 23 for the third cylinder is constructed with an inclined side 62, which is suitably separated from the vertical side of the partition or block 60, and between the part 60 and the inclined side of the journal-block 23 is a slide-block 63, having an inclined side 64. The screws 66 and 67 vertically arranged, as shown in Fig. 3, have thread engagements through upper and lower portions of the side frame and have inner end contacts against the top and bottom of the said inclined-sided slideblock 63. The outer journal-blocks 21 and 24 are operated against by the horizontal longitudinally-arranged adjusting-screws 68 and 69, which have thread engagements through the portions of the side frame which constitute the end boundaries of the recess or slideway 12 for the journal-blocks, and the journal-block 23 is capable of a horizontal ad justing slide movement toward and away from the second cylinder. 7

Preparatory to running the machine for any required class of work the first cylinder is adjusted in proper proximity to the second one by means of the screw 68. The third cylinder is permitted by a raising or lowering of the wedge-shaped block 64 to be properly closed to or hard against the second cylinder, and the fourth cylinder is set up to the third cylinder by the adjusting-screw 69, the screws 68 and 69 being turned to relieve the journalboxes 21 and 24 as occasion may require.

The disk-like members or pulleys of the substantially cylindrical rotary part carrying the .grippers 42 support and propel the carrier-tapes 70, which run therearound with their upper and lower courses or runs convergent, as represented in Fig. 2, these tapes at the forward or delivery end of the machine running around an idler-tape shaft 72 and causing the rotation of the latter. This tapeshaft has a series of disks'or pulleys 73 sidewise offset from the point of contact of the tapes with the tape-shaft, which disks or pulleys are of considerably-increased diameter and have consequently much greater peripheral or surface speeds than the tape-shaft itself.

A series of wheels or disks 75, carried on a horizontal cross rod or shaft 76 therefor, have frictional rolling contacts at the top edges of the aforementioned disks 47.

The sheets of paper entered at the feedingin end of the machine first grasped at their leading edges by the grippers of cylinder 1 are carried rearwardly and upwardly to be taken by the grippers of cylinder 2, which convey the sheets upwardly over and downwardly around to be taken by the grippers of cylin- "der 3, which retain their hold on the sheets wheels 77 77 are forwardly fed, so that by the time the forward edges of the sheet come between the disks or wheels 73 and their rear edges have passed free of the rolling engagement between the disks 77 and 47. The instant that the forward edges of the sheet become engaged between the disks 73 and 75 an accelerated movement is imparted thereto, so that they are shot into the receiving-box 80, each being piled on the previously-delivered sheet before a succeeding sheet comes into the box, and thus the requirement of a girl at the receiving end of the machine is done away with, it only being necessary to have one attendant located at the feeding-in end of the machine.
